9. Of course!

From the article in the OP:

Adults should have a pertussis booster every ten years. I got my TDaP booster a couple of years ago. Just two months earlier, unbeknownst to me at the time, a little girl in Belgium named Lore Darch died from pertussis at the age of 83 days. Her father, Danny, wrote a diary for her as a memorial. Read it if you can. I did, and my heart aches so hard it’s a physical pain.

Like David and Toni McCaffery — who lost their daughter Dana to pertussis — Danny and his wife Katrien have become vocal advocates for vaccination.

If you haven’t had your booster, you should talk to your board-certified doctor and see if you need one as well.

Of course, when the McCaffery's spoke out, the anti-vaccination brigade fought back:

So it was no surprise that they flooded the station with complaints about one-​​sided journalism, “Big Pharma” conspiracies, and misinformation about court cases in the US proving there is a link between vaccination and autism. You can read some of the feedback on the AVN website, published as part of a story called “Channel 7 — one-​​sided reporting.”
